The Missouri University of Sciences and Technology Reactor (MSTR) is pool-type research reactor which operates up to 200 kilowatt (kW). MSTR used for training and educating nuclear engineering students at Missouri S&T. A several of nuclear researches and irradiation experiments have been conducted in MSTR for example, neutron activation analysis (NAA), neutron radiography, radiolysis, image processing, etc. MSTR initial criticality took place on December 9, 1961. The first power level that MSTR operates at, was 10 kW. The power level alongside the core configuration was upgraded to the current ones, see Fig. 1. MSTR used light-water for moderation and natural convective heat removal. MSTR core consists of 9_6 aluminum array grid plate, nineteen fuel elements, one source holder, a single beam port and three irradiation facilities namely, bare rabbit tube (BRT), cadmium rabbit tube (CRT) and hot cell (HC).
